鸭嘴龙鸭嘴龙hadrosaurs一类较大型的鸟臀类恐龙。最大的有15米多长。鸭嘴龙的吻部由于前上颌骨和前齿骨的延伸和横向扩展,构成了宽阔的鸭状吻端,故名。鸭嘴龙头骨高,其枕部宽大,面部加长,前上颌骨和鼻骨也前后伸长,嘴部宽扁。前上颌骨和鼻骨构成明显的嵴突,形成角状突起。上下颌齿列复排,每个额骨上有45~60个牙齿皆垂直复叠。珐琅质只在牙齿一侧发育。颈椎和背椎椎体为后凹型,背椎神经弧较高,尾椎侧扁,其神经棘和脉弧皆很发达。肠骨的前突平缓,后突宽大,耻骨前突扩展成桨状,棒状坐骨突几乎成垂直状态。前肢短于后肢,前足的第二、三、四趾较第一、五趾发育。后足的第一趾消失或仅有残迹,而第五趾完全消失,第三趾蹠骨较长,后足已发育成鸟脚状。另外,前后足各趾皆有爪蹄状末趾。鸭嘴龙是鸟脚类恐龙最进步的一大类。在亚洲及北美洲等地,晚白垩世的鸭嘴龙化石到处都有发现。鸭嘴龙类可分为两大类群:一是头顶光平,头骨构造正常的平头类;另一类是头上有各种形状的棘或棒型突起,鼻骨或额骨变化较多的栉龙类,如拟栉龙。除此以外,还有变化不大、较原始的鸭嘴龙及前颌骨和鼻骨特化成盔状的鸭嘴龙。鸭嘴龙主要以柔软植物、藻类或软体动物为食。一般是双足行走。前足各趾之间有蹼,以利水中运动。拟栉龙复原图
